Nicolas,
Let me give you another example this is like ordering a personalized teddy bear for a baby and BEFORE adding it to the cart you choose the color and then write in a box "the name of this baby",and then add it to the cart.
So maybe it can be done by creating charasteristics,variants...I don't know how we can do it in Hikashop.
Please see the link page below as an example,do you think we can add a variant (blank box)where customers can write a 20 words to customize their order?

see the personalized tab.I don't want the add and personalized but just a blank box to write the text or the words and under the box it is written how many characters can be included.
may be a better example is:

If this worked I can do it too to gift messages.
